    Stability of new rice genotypes for grain yield
    (Kerala Agricultural University, 1994) Elsy, C R; Rosamma, C A; Prabhakaran, P V
    The yield potential and grain yield stability of three medium duration rice cultures were studied over six cropping seasons at the Regional Agricultural Research Station, 1'attambi. Cul-8770 and Cul-8772 had shown stable high yield potential over the seasons. These two cultures recorded high mean yield and lesser deviation from regression. BR-51-46-1 with its lower mean yield and higher deviation from regression, is not suited for general cultivation, especi.illy during kharif season. The added advantage of Cul-8770 and Cul-8772 is the good straw yield and red bold grains which are highly preferred in Kerala. All these attributes make Cul-8770 and Cul-8772 suited for release as varieties for general cultivation.
